E.g. I have 3 email accounts, 1 personal and 2 business/company accounts. I want to schedule the personal account to fetch mail 24h 7 days a week and the company ones e.g. from Mon-Fri from 7am to 6pm.

"Unread" isn't a search option, so we can't integrate it into a smart folder. This is valuable, for example, to set a workflow where i can find unread or starred items to a particular address. I use this in Apple Mail instead of my inbox and thus I see all new messages, or ones I've flagged for later.

I tried Airmail which is better than Thunderbird. I forward all emails from other accounts to my gmail account. When replying to those emails out of Thunderbird it uses the original outbound email service.

Unfortunately, in Airmail I cannot create email account only with an SMTP server only.

I use Apple Mail and all my mail is flagged with a different colour for "business",Interests" etc etc. I prefer to use Airmail though and would like it to pick up Apple Mail flags and labels and allow me to use the same in Airmail.
Thanks

If you look at gmail, the difference in styling between READ and UNREAD messages is very clear, i find the blue dot for unread is messy and doesn't help clearly define. A darker background would be clearer.

Now that Apple has allowed iCloud accounts to have any user name, I have used my Gmail email address (in full). When I've set up Airmail, I have been told I cannot have a Gmail account and an iCloud account with the same user name ... which is silly, because it is with 2 different providers! Please allow this functionality

Hi. Maybe it's just me, but I'll often leave Airmail open with a search term in the search bar. Thus, later on, a quick glance at the program makes it look like there are no new mails. I have to stop and consciously check to see if I'm searching for something and that's why.

I would like to see some kind of visual cue that a search is in progress - maybe as simple as dimming the top bar and/or highlighting the search box. Just something so you can see when you glance that you're not in the Inbox.

With a large number of local folders, going through the entire classification tree for every single email which should end up in the same local folder is boring... (for example one original email and its answer are in two separate Imap folders : Incoming mail and Sent. I cannot select them at the same time and direct them to the same local folder once treated...
Mail.app has this function : "move to the last folder used", and once a series of email is treated, sending all the series of emails to the "last folder used : XXX" would save time.

Just like it sounds - create custom actions/workflows through chaining of built-in actions.

Example workflows (that I currently chain manually):
1. In the message list: Send to OmniFocus, then Archive.
2. In the Compose windows: Send Email, then find sent email, and send copied email to OmniFocus

I many mail conversations, you often end up, where you are awaiting a reply on a mail from the recipient. Those kind of mail threads tend to stay in the inbox.

I would like a feature, where I can mark a mail thread as "awaiting reply" and the thread should then be hidden (like in snooze) until I get a reply and at that point, the thread should move back to the inbox.

The even more advanced edition of this idea is, that I can define a "max wait" time, so that if I have not had a reply for say 1 week, then it will move back to the inbox and get my attention again, so I can reach out and poke the recipient for a reply.

With the apple mail and the iPad version airmail you can select photos directly from the photo app, and they are loaded at a reasonable size into the letter, and the photo is displayed without having to download an image,
I would prefer this method, with notability you can even re-size and move the photos, that would be the ultimate, however if I ever require to email a photo along with a letter, I could always use another app,
